effect of the mill speed on cyclone efficiency

  • the effect of particle size and input velocity on cyclone separation

    Abstract: Cyclones have been regarded as one of the simplest and cheapest type of separator on account of their high efficiency, adaptability, and relative economy in power. Cyclones have been widely used in different industrial processes. The literature reveals that the cyclone efficiency is dependent on the particle size

  • Cyclonic separation Wikipedia

    When removing particulate matter from liquids, a hydrocyclone is used while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate mixtures of solids and fluids. The method can also be used to separate fine droplets of liquid from a gaseous stream. A high speed rotating (air)flow is established

    The manner in which the air and product enters the cyclone also affects its efficiency. Kice pioneered the concept of keeping the inlet centerline tangent to the outside edge of the cyclone. This smooth introduction reduces turbulence and increases efficiency of Kice cyclones. Kice refers to this as an externally tangent inlet.
